Introduction: K'NEX RBLTR V.1 (Red's Breach Loading Tactical Rifle) (Build)

Picture of K'NEX RBLTR V.1 (Red's Breach Loading Tactical Rifle) (Build)

This is my "Toy Rods and Connecters Contest" entry #1, the RBLTR (Red's Breach Loading Tactical Rifle). This is probably the most powerful K'NEX gun I have ever build, with range that reaches over 70 ft. It was a fun build, and is not at all piece consuming. It uses internals that closely resemble gtrain's G36C mech.

Some features of the gun are:
- Great range: 70 ft.
- Permanent fore-grip
- Nice sights
- Great pin pull
- Nice attachment bar
- Breach loading
- Shoots yellow rods

Now, lets move on to step #1...

Step 1: Main Body #1

In this first step you will be working on the right side of the main body, and part the internals. If you have any questions, please do ask. Keep in mind that you will want to read all of the image notes, they will help you.

Step 2: The Fore-grip

In this step you will be building the permanent for-grip. I was too lazy to take it all apart, so if you have any questions, do ask.

Step 3: Main Body #2

In this step you will build the connecter set that sits underneath the pin (when it is pulled and ready to fire). Again, if you have questions, pleas ask.

Step 4: Handle / Pistol Grip

In this step, you will be building the handle and the comfort bar. Again, I was to lazy to take the handle apart, but it is pretty easy all the same.

Step 5: Main Body #3

In this step you will place the left side on the gun.

Step 6: Sights and Attachment Bar

In this step you will be creating the sights and the attachment bar. If you lack any understanding, I will inform you.

Step 7: Banding and Adding

This is the last step. In this step, you will add the additions to the gun, and add bands to make the gun function. Go ahead and ask questions, as this step might be harder than you think. Oh, and BTW, if you have noticed any spelling or punctuation errors, pleas tell me.

The Knex Inventor (author)2016-06-08

Nice! I will build it sometime to learn about the breach loading mechanism.

Guys please check out my gun where a breech load mech loads the internal mag

Ok I will and I have a question, did you change your username? Weren't you jarebB?

I just built this (no pics unfortunately as phone camera is broken) and I absolutely love it! It only took around 2 hours to build, including modding because I wanted an actual sight, and it fires exceptionally well, has a really long and really smooth pin pull, and can hold ever rubber band I can jam through the firing pin.

Range: around 55ft holding it straight or up to 100 (!) at 45 degrees.

Definite must-build for anyone who is looking for a powerful single-shot.

Awesome dude! That's great to hear! Thanks much man!

Sorry bro, but this has been gone for months.

Is it a single shot because i am looking for a solid secondary

I can't believe I'm sayin' this, but on the scale of good K'NEX weapons, this is somewhere in the middle. Neither good, nor bad. If you are looking for a solid secondary, I'd go with the S2 Bolt-Action pistol. The RBLTR V.1 is a nice gun overall, but it only gets good range because its single-shot/breach-loaded + 2 size #117 bands.

Add mine in if you want...

Give me a minuet, I'm kinda busy doing math (or I should be busy doing math)...

pongopeter826 (author)2013-09-17

Is there an Easier way to pull the pin back?

To tell you the truth, I don't know. I bet, if you put your mind to it, you could figure something out.

hunter999 (author)2013-08-27

Does this use 'broken pieces'?

Correction, it uses some, but I don't think any are needed.

Ok, I will build it then! :) although I don't have that red bendy rod for the sight. I will post a pic when I have made it

Please do, but on one condition. I would really like it if you wrote a review 'ible / forum topic on it, with a picture of the gun that you built... Could you do that?

Yea sure! I'm already building it! I will let you know when I have wrote the ible review for it!

Congratulations for being selected as a finalist in the Toy Rods and Connectors Contest!

Thanks, you too bro, you did fantastic! =D

No problem. =D

mustangalex99 (author)2013-07-23

I'm new to K'nex guns but this is an awesome gun, but how do you make the firing pin?

Thanks bro, I am glad you like it. Here is how to build the pin:

First take a rod of sufficient length (preferably a black rod).

Then take a connecter (this one uses a red connecter) and attach it to the black rod.

Tape them theatergoer so that they wont come apart easily.

The take a large broken rubber band and wrap it around the connection you have made with the tape, the rod, and the connecter.

Add bands into the holes, and band it to the gun. Now your done.

Do these instructions help at all?

sandroknexmaster (author)2013-07-12

I made one too! :D
You did a great job on the instructions, everything was clear (just the foregrip and handle but it was still ok).
And it shoots AMAZING!
Great gun!

Really, that looks awesome! Good job! What range do you think you got?

About 15 metres (50 feet) at least, and up to 25 metres (80 feet).

No problem.


Please, please, please do!

XD, I'm sure I did. Knowing me, I probably was going to fast.

No, it is not. Not in the least.

hunter999 (author)2013-07-03


Thanks man. =D

BaneAlGhul (author)2013-07-04

Definitely building this after I finish up the rest of my PDW.

Pleas do. =D

JonnyBGood (author)2013-07-02

"any spelling errors, pleas tell me"   ; )
I know that breach loading gives you a boost in range, kinda why I'm excited about my project. It singles out every round before you fire it.

XD, oh I get it. LOL

Well was that intentional or not? Regardless it was well placed.

I don't believe it was intentional... =S

XD, thanks.

No problem. Anytime. Voted for you too. I'll be getting Competitor III up for this contest soon. I feel late and kind of intimidated. You guys were very ready for this to start, I should've had my ducks in a row.

unless you ae following me

I believe that I am following you...

Ummmmmm just checked my followers list and you aren't on it btw I posted 2 new guns
